Presence Patrol.

Afghan children walk alongside Lance Cpl. Jacob Kartchner, a team leader with 3rd Battalion, 3rd Marine Regiment, and 28-year-old native of Long Beach, Calif., in the hopes of receiving candy from Kartchner as he patrols with fellow Marines and Afghan National Police outside the Hazar Joft Bazaar here, April 8, 2012. On the patrol, the Kilo Co. Marines partnered with members of the ANP to maintain security in and around the bazaar, one of the busiest commercial centers in Helmand province's Garmsir district. Their partnership is a vital part of preparing the Afghan National Security Forces to assume lead security responsibility in Garmsir.

Please note that you don't see an Afghan Policeman in the picture.  That's what I call outstanding force protection.
